To allwlwm it 'Nm3/ commen y Be itknown that I, ARSENE SAULNLEB, a citizen of the UnitedA States, .residing at Wlaltham, in the county. of MiddlesemState of Massachusetts, have invented `a certain new and useful Improvement ,in Clocksfor Warping Machines, of` Whichthe,.follow. ing is` a specification, `reference being had therein to theaccompanyinggdrawings. .l

The invention hasrelation to the sooalled clocks which arejemployed infwarpingiand other machines `for. thepnrposea of .registering the length.of.,assembled tthreads which passes4 through .annachineypand of bringing about the Stoppillgiiofl llleilma when a ypredetermined measured length has passed. It further has lrelation to, clocks on the order of lwhat aretermed lease-clocks, these being contrived tol cause stoppage of the machine at intermediate points during the,passage of.the.total predetermined lenvth of assembled threads, for the purpose o enabling` lease-.threads or cords to be introduced latpredeterminedintervals among thel assembled ithre 2nls. In usual practice, the clock of a lvisal'ping machine comprises a spirallygrooved barf rel, called a scroll, and a follower` engaging in the spiral grooveof the scroll. ,The scroll is geared with a measuring roll which is rotated through the Contact of the traveling yarns with its periphery.` and @theifollower is traversed by the thread: of4 the |scroll as the latter rotates, and arranged t0 act in connection with4 other parts with which it is associated to indicate into action at the required time or times the stop motion mechanism of the machine. yIn the ease of some warping machines the Vclock brings :shout the stoppage of the machine only on the completion of the required total length of assembled threads. In the operation of n .leasewarper the clock causes arrest of lhc machine after a certain number of. yards has passed through. whereupon the attendant introduces lease-threads or cords and restarts the machine, the stoppage, introduction of lease-threads or cords, and restarting being repeated at intervals until the final automatic stoppageof thcmachine which indicates the passage of the total predetermined length.

Trouble and loss are experienced often in practice in consequence of accidental dis- ,A VL placement of4 the..follower of a clock relative to ,the turns of-the spiral of the clockscroll. Suchdisplacement results in false registration by. the clock, and in inaccurate measurement, involving for instance either too many4 or. an insuicient number of yards of threads being;1 passedthrough the machine. Displacement .is not detected readily,` and :usually passednnobserved so that theerror4 is not discovered until .later on ,in the g handling or', use. of `the assembled threads.' ism .1; yVVhat--has just' beenstatedwvill be more clearlyapparent after, reference to the practicein connection ,withbeam-warpers A beam ,warperis employed to,wind.,threads o-n a `beam,l `from spoolsmounted in aereel, until ythe .required lengthof threads has been thus `Wound.H Thenumber of threads thereby Wound Aupon the beam is 'a fractional part oi theentire number ofy threads required tomake :theicontemp-lated warp, and constitutes one sofcalled, sectionof the warp. In like manneiias many sections arewound upon ,other beams; as are ,necessary to make up the required totallothe threads for the said Warp. All of: the sections are combined at the.slasher, and afterpassing all togather ,through the latter areiwound upon a single beam in readiness to vbe placed in a loom. .(Dbvionsly all .the sections of a warpishouldbeof the samelength. If one or more sections, through errordn the winding thereof upon the corre onding section beam or beams, should be either shorter or longer than the others, loss or trouble would result. Theexcess,ofy1ength in thecase ofthe longer section or sections of a Warp would become Waste.v

The object of my invention is to prevent displacement of the follower. and to this end my invention comprises. firstly. means for locking the follower normally from beinter disengaged from the spiral nf the scroll; and secondly. means for keeping the follower in working relations with the proper turn of thc scroll-spiral by preventing entry of the follower into the wrong turn in passingr from a lease-groove, the latter means preferably heingso oontriredes to prevent the follower'from enga ing with the wrongr turneven after being li ted from the normal position'. y r

illustrative embodiments of the two porengaged, lands upon the rib between the turn last occupied by it and one of the adjoining turns, and remainssnpported upon such rib for awhile -beforeidropping back into Vthe former turn. The exactlength that has passed-through the machine is not obvious .upon inspection of the wound mass-of tl1reads,=a.nd can only be approximated by weighing such mass. Consequently,errors in length frequently pass unobserved-for the time being; when suspected or;` known, the extenbthereof--is not easy of ascertainment and usually accuracy in the correction thereof is diicnlt of.'-accom'plishment.= -I the follower, after having been lifted, dropsA into an adjoining, turni yeitherprecedmg or -following the tunffromiwhlchrritwas lifted and eitherdirectlyiin'be' 'returned-.toward ;.Working- .reltions' :zor a rf; iilst i -having landed uponrthenintermediate rib,the total length passed through thema/chine up "to: the tn'al stoppage. mayv bezgreatly -nzexoess .or greatly below'therequiredlengthrff --J usthow much, can beiasoertai'nedionly by weighing what has passed thrugh;the-extent'bf.the error cannotbei determined- ;merely from Ilooking atthescroll vindiollox'rer.A

Referring lnow tothe lirst portion -of the in'ventionpnamelm. the follower-lwk for holding the' lfollower from being disengaged -fromJ the spiral-of thejsm'oll.:.;.= 3-'. y. .-The fprecise' consti-notional' form of -ollower-lock adopted fin-practice,and the prei cise-pla and mannerof application iofithe same, may vary-more `or-,less`,--lmdwill be governed -byfthe mode of operation, etc., 'the warperfcl'ock, or of the .warperitself, and. bytheviews and requirements of builders and users'o'f the meehanism.- @The illustrative embodiment of this portion ofthe invention-which isr'represented in the 'drawings-comprises a form of follower-lock which iswdapted-more es pecally for use in connection with' a warperclock in which, as ordinarilyfin practice, and as more or less fullyset forth in the preceding description. relative traverse between the serolliand the follower is providedvfor liyarranging the follower to 'traverse lengthwise ofthe scroll, and in which the -follower is movable lengthwise of the axis of the roclrsheft 17 of the indicating rocker and combined with the said roclsha ft in :i munner which causes them to turn in unison around the said axis.

The illustrated follower-Lick is arranged to lock the indicating rocker from being rocked in the nuulner that is requiied in order to permit the follower to lie disengaged from the sr.roll-groo\'e; more specifically, it isarranged for direct cooperation with the rock shaft 17 of the said rocker. lt comprises a movable dog. a, adapted for coaction Awith a tooth or vshoulder b in connection with the said rockshat. Such 'tooth construction and specific or Shoulder in this instance is. provided upon a collarcthat is mounted upon the roekshai't and held fast thereon 'oy inenns of' :1 serien- (L A spring e acts on the locking; dog with Ea tendency to more it into eng-aging position, and a wire or rod f extends upward from the dogito a point where it conveniently muy be reached by the hand of the attendant. The tooth or shoulder b is so related to the locker, and the dog a, to the snid tooth for shoulder, that when vthe follower projection is in the scroll-spiral the tooth or shoulder I; is presented in such position to the dog that it is adapted to be and is engaged by the dog, and by such engagement the follower is locked from removal from the scroll-groove because the rocker cannot be turned far enough to allow the follower to be lifted suiciently to withdraw the projection l5 from the scroll-groove. At the sime time, the relations and mode fof engagement of the dog and tooth or shoulder aford freedom to the follower to drop slightly when the crogroove 10, otherwise termed lease-groove, is presented to the follower projection 15 in the rotation of the scroll, and also when the final stopping notch 10" is presented in position to receive the said projection. The wire or.rod f provides for nmnuztl control of the lock by enabling the dog to be lifted clear ofthe tooth or shoulder whenever requiied. l-When the dog is lifted, as by means of' the said wire or rod, the follower is unlocked and may be swung out of engagement with the scroll.

The tooth or shoulder L is slight-ly undercut, as shown in Fig. 5, and over-hangs the engaging end of the dogr a to an `Vextent snficient to guard against the dog being shaken or otherwise accidentally dislodged from the tooth or shoulder While theifollower occupies the slightly dropped position assumed by it when projection 15 enters the cross or lenscgroove 10 of the scroll.

`Referring now to :the secoml` portion of the invention, namely the means for keepingr the follower in correct workingr relations with the proper turn of the scroll-spiral even though lifted from its-nornnxl position, and for prevent-nigr oni-ry of the follower into the wrong turn of the Scroll-spiral in paing from :i lease-groove in the scroll For the attaimneni of Hic pnrinioses just mentioned l provi'le'in #sloom-(ion with tln; follower what l call :in alinei. Tn the frase of this device` as also in that of the follower lock, the precise minslrnetiounl forni thereof, and the precise inode of combining the same with the follower may be varied more or less in practice. In the illustrativo einbodiment of this portion of the invention that is shown in the drawings the aliner` therein marked i, is of the general form of' a blade, and is'movably combined with the follower by being pivoted at i, at one end thereof'` to the opper portion oltlie lollowor :ii-1n so that the aline-1' swings down toward the peripheryr ot' the scroll and its under edge enters the scroll-grom'e. The outer end ol' the aline-r is extended to form a ronvenient handle h v means of which the aliner may he moved by hand when required. and also for the advantage of the increased weight, the weight of the aliner aiding to keep the said edge in the groove. In this instance the aliner trails in the scroltgroove, in the same turn of the latter that is cocu; pied h v the follower-projection 15. By reason of the movable connection of the aliner with the follower, the aliner remains in the scroll-groove even though the follower be lifted snflicientlvY to withdraw the projection l5 from the groove. Consequently, the return of the said projection to the particular turn of the scroll-groove from which it was removed is ensured.

-In the operation of a lease-warper; and following the automatic stopping of the machine which results from the dropping of the follower-projection 15 into a leasegroove, and also after the lease-threads or cords have been inserted amongr the threads, it is customary to insert a stick into the lease-groove under the projection 15, and permit it to remain there temporarily following the restarting of the machine. This stick serves to support the said projection high enough in the lease-groove to enable the projection to pass from the lease-groove into the continuation of that tnrn'of'the spiral groove in which it was containedprior to dropping into the lease-groove; Comparatively often, as a result of carelessness or lack of skill, the stick in being inserted hits against the projection 15 and thereby, in the case of warner-clocks' nnprovided with the second portion of my invention', moves the follower sidewise, that. is to say in the direction of the length of the scrollaxis, thereby shifting the projection alongr the lease-groove into a position causing it to enter a wrongr turn of the spiral groove, This, if unobserved. makes a difference of one or more (as the case mav be) turns of the spiral. representing u difference of a large number of yards of. threads. The aliner. by occupying a position in the spiral groove while the follower-projection is" in the longitudinal cross or leasegroove. prevents lateral displacement of the follower :it such time. either through being hit or pushed hy the stick. or otherwise accidentall)l disturbed h v the attendant or some other person about the machine. or' as a result of jarring ol` the mechanism.

The :diner may either follow (as in the present instance) the 'follower-projectionin the spiral groove. or precede it It preferably is movablv combined with the' follower in order that it may gravitate' Orbepressed as hy :i spring into the spiral groove, and in order that` normally it may remain thereinwhen the follower is raised; However, it may befxedly combined with the follower. The extent to which the aliner is separated fromthev lollower-projeetion 15 may vary more or less: in case the nliner is a fixed part, it may be :in extension from the Said projection.
